Ark42 asks: "Did the Unisys patent on LZW expire back on Dec 10, 2002? Does that mean we can all write GIF software royalty free now? From what I can gather, Unisys only lists patent number 4,558,302 for covering LZW, which was filed on Jun 20, 1983 and issued on Dec 10, 1985. According to this site patents filed after Jun 7, 1995 last 20 years from the file date, and patents on or before then last 17 years from the issue date. That means the LZW patent expired on Dec 10, 2002. Am I missing anything?" A deadline of 2003 was given in this earlier Slashdot article. Assuming .GIFs can't follow in the footsteps of Mickey Mouse, will the popular image format now be "web safe"?

jdclucidly asks: "I am a network administrator for a small non-profit (about 50 employees). I would like to roll Mozilla 1.2.1 out to all of our desktops. We don't have a single ghost image because the computers on site are too varied. Yes, I did my Googling. The source for the installer is just huge and mind boggling. Is there something like a Mozilla Administration Kit that will generate custom Mozilla installers? If not, would people on Slashdot be interested in starting a new project to make such a kit?" If you were going to deploy a "branded" version of Mozilla, company-wide, how would you do it, especially if you had to worry about a mixed OS environment?

ylsul asks: "Like many of you, I find myself working from home a lot, and I usually end up slouched on my couch with my laptop. Have any of you out there found the 'perfect' way to hack and slack at the same time? (maybe something like this?)"

dogmeant asks: "I have yet to see MOM (message oriented middleware) offerings on Linux much less open source projects that address the same. And while we're at it, what about tools that address SOA/BPM (Service oriented architecture/business process modeling) type architectures on Linux? Is the Open Source community ready to take on challenges like this?" If anyone else out there has this particular itch, maybe this will be another niche in which Open Source software can catch some Enterprise mindshare.

Inexile2002 asks: "I've been asked to assist a consultant on a project using VMS and basically have four days to figure out enough that I'm actually of some use. (We're not doing development, just security reviews, so I'm not totally screwed.) Originally I was going to ask for advice on how to start teaching myself VMS from scratch including best books and support websites when I realized that there is a more generic issue here. What are people's thoughts on learning a new OS and learning it fast? Have people found optimal ways to pick things up quickly, get a familiarity with commands and underlying logic? How about learning the basics when you can't actually install and play with the OS in question?"

An un-named reader asks: "For various reasons, I've been out of the workforce and IT industry since 2000, before which I was employed as an NT-based sysadmin at a large Canadian company. After moving to NYC I found the market flat and got into other work for a while. Now I find myself wanting to get back into IT professionally, but my resume is getting no nibbles at all (over 800 resumes submitted in the last year or so). As a result, I decided to take some training courses to get me back up to speed not just in the W-Intel world, but give me some usable knowledge of Solaris, a CCNA and Checkpoint. Here's where things bogged down. Are there any decent schools out there who have good facilities, good instructors and do more than 'teach-to-the-exams?"

smurfeater asks: "I know this topic has come up in the past, but with the IT market as it is, it may be a good time to review. I have been working at my firm for over a year now and today they came to me with a Confidentiality and Non-Compete Agreement. To make a long story short...due to their SNAFU they are allowing us to modify the agreement a bit. What things should we ask to be included, excluded and what time frame should it cover?"

aszoth asks: "I working on a project that is going to require approximately 4 hours of video recording per day for about two months. We are currently using DVM tapes, however the extraction and compression time has left us with a large library of tapes un-converted. We are considering other methods, in particular real time MPEG 2 or MPEG 4 Compression. We also would like to be able to slow down our frame rate from the 29.7 fps to something along the lines of 5-15 fps. I am wondering if any one has any suggestions on possible ways to do such compression (or get similar results) with a Linux box. Thank you for any help you can give."

blackcoot asks: "I've just spent a couple very frustrating days trying to figure out what 'unexpected async reply' means and fixing it. The problem is a result of the fact that X11 simply isn't designed to handle events from more than one thread at a time. Why? Given that more and more often, people are writing multi-threaded GUI applications, are there fundamental design decisions in X11 that make dealing with receiving events from multiple threads simultaneously, impossible? Or was the protocol never designed to handle concurrent updates? More to the point, is there an easy way in Qt (short of deriving a new widget for every widget and overriding it's paintEvent to lock the library first, paint, then unlock as Trolltech's docs seem to suggest) to make this problem go away?" I'm not sure if things have been done in recent revisions of XFree to fix this problem, but this message, from February of last year, might help some of you out that are suffering from this problem. Any ideas if this problem has been fixed in recent versions of XFree?

why-not-now asks: "Recently there's been a lot of talk about open source/free software that enables your PC to act as a DVR, all-purpose media player, DVD player, CD player, MP3 player, etc... not to mention the ability to play all sorts of video games (if you know where to look). The idea of the set top MAME console is nice, but with a little TV/Audio out, a little know how and the right software, are we currently able to put together a free version of the big convergence media center others are trying to do?"

Sean Cope asks: "I've used a computer for a number of years, now. I've never been interested in programming, but after seeing the link to the demo DVD, my interest is in full bloom. If you were interested in creating a demo, where would you start? What books would you buy? Keep in mind, I've only used a computer for communication, and games up until this point."

Need for Speed asks: "I just moved to the boonies and I'm looking into DirecWay from Hughes. I'm too far from my CO for ADSL and IDSL is too expensive. DirecWay requires their modem to be connected to the USB port and their software to be installed on the client. Multiple connections can be supported by enabling ICS (Internet Connection Sharing) in Windows on that client. I then can connect a router/etc to the ethernet card on that client. I don't want to sacrifice my Linux box to do this. A direct connection from the DirecWay modem to my Wi-Fi router would be nice, but it doesn't seem to be an option here. Has anyone successfully configured DirecWay without installing the DirecWay software and connecting the DirecWay modem directly to your computer?"

1101z asks: "Well I work for a public access station in a city where a second cable/phone/internet company has moved just started operating. Part of there deal with the city was to let us have (for free) dark fiber links between several location in the city and our studio, so that we would be able to cablecast live from those locations. As the computer guy I would like to be able to interconnect computer networks that already exist at several of those locations, when we are not using the fiber for cablecast. The question is what is the cheapest way to build a TCP/IP network over this dark fiber." I wonder if the fiber being used is related to this story, from a month ago?

crank asks: "I've recently hoisted an antenna high upon my roof, since I'm bored with listening to the mega-watt corporate radio stations and instead and enjoying great, niche college and NPR stations. What I need is some sort of TiVo-like radio device, which will tune to the appropriate radio station and record to the hard drive (ideally to MP3 or Ogg Vorbis formats). Then, I could dump these to one of the many portable devices or stream from a computer for later listening. This is especially important with stations that change format frequently throughout the day, such as KFJC. Any suggestions? I think the tricky part would be integration of the FM tuner. I've had limited success with leaving the radio station pre-tuned to the station I want to tape, but I'd like something smarter that would power up, capture the program, and then power down."

bluelip asks: "Do any cards PCMCIA cards exist that will function as a network diagnostic/certification tool? Our Lancat and Microtest/Compas devices are aging and need to be replaced. It would be ideal to have a card we could plug into our laptop or Zaurus to use as a replacement for our bulky devices. I have seen this, but it doesn't contain all of the functionality we need. I would like the card to be able to determine hardware facts such as line length, what type of device is on the remote end (workstation or switch), next, crossed wires, etc. Another benefit would be if it functions like a normal NIC so we can use the same card for arpwatch, ethereal, and other tools. Does such a beast exist?"

Rsriram asks: "At our company we have named some of the conference rooms with names of software innovators. The names include Ken Thompson, Donald Knuth, Ada Lovelace, Dennis Ritchie. We need to name 10 more rooms and I was wondering who Slashdot readers would think are the top ten software innovators. Not computer hardware but software. I was thinking Von Neumann, and Linus Torvalds would find a mention, What about Watts Humphrey?"

millisa asks: "With the tightening economy, technology workers are finding themselves picking up extra tasks in the workplace which in turn can raise stress and detract from the ability to relax. Many of us are strapping an assortment of gadgets that beep, vibrate, and blink at us (and most of them aren't the fun kind) with the purpose of on-call response at any and all hours. Where does the restful bedroom exist? What I'm looking for are ways other nerds in the community have made their bedrooms into a place where they can release tension of the day and improve their overall quality of life? What measure have others taken to be considerate towards that signifigant other (in order to keep them being the signifigant other)? Hidden receivers and speakers for mood music? Ambient lighting? Walled windows and soundproofing? What's in your de-teched sanctuary that keeps the minimum for you to fulfill your job obligations? Economical suggestions are quite welcome!"

matth asks: "So which is better? Analog or Digital for your cell phone? The cell phone companies would like you to believe Digital is better... but is it really?" matth makes his, in this article. Would you care to make yours?

josquint asks: "Does the Computer Service/Repair field need to be regulated? This is a question I asked myself after spending a day off from my position as Lead Technician at a local computer shop, in an auto repair shop and a hair salon. In both places, I noted that all the employees had their trade credentials displayed for all customers to see. They are not only displayed as a matter of pride or to gain customer trust (as my A+ and Network Security certificate is) but as a matter of law. This regulation, to me, makes sense. If you're going to pay good money to have your automobile repaired, it better be by someone trained and proficient at doing it (otherwise I might as well do it myself!). Also, there is a matter of safety --an error in repairing a car can easily result in injury or death of quite a few people, so some accountability is needed. The salon regulation, to me at first, seemed like the usual overkill large government regulation. However, it too is a matter of safety to the clients, as the chemicals and equipment (tanning beds especially) can also do harm if used incorrectly. Would you view regulation or mandatory certification as a good thing in the computer repair/installation/maintenance world? What kind of regulation would you like to see, if any? How and at what level would it be implemented and enforced?"

Ethically Challenged asks: "Under the guise of recent legislation everyone at the publicly traded software company I work for is being asked to sign a 'Code of Business Conduct and Ethics'. In part, we have to swear to the following: we should not use company resources for any non-business purposes (I probably can't even write this); we must disclose to the CFO any relative that works for a customer, competitor or vendor; and, we are required to narc on coworkers who we suspect violate the code in any way. Are developers at other companies being asked to do this? Does it bother anyone that lowly workers like me are being asked to sign these things because executives are too immoral to behave themselves? Isn't all of this a colossal waste of time since most of it is common sense and it's pretty clear that the bad guys will ignore it anyway?" Most of this stuff sounds like the boilerplate protections most companies put in their employee agreements in the first place. Since you generally have to sign such agreements before you get your first paycheck, this new initiative seems rather redundant to me. Can someone more clued-in explain the justification behind this one?
